  • Process and monoclonal antibody for the specific determination of pancreas alpha-amylase in the presence of saliva alpha-amylase
    Patent number: 4939082
    Abstract: In body fluids containing saliva alpha amylase and pancreatic alpha amylase, pancreatic alpha amylase is determined with a monoclonal antibody which specifically binds but does not inhibit saliva alpha amylase and which has a cross-reactivity of 5% or less toward pancreatic alpha amylase. The monoclonal antibody binds salvia alpha amylase to form a complex which is separated to permit determining pancreatic alpha amylase with an amylase detection system. The complex may be separated by precipitating with a precipitating agent such as an anti-antibody or protein A, or by immobilizing the monoclonal antibody on a solid carrier.
